General Discussion / Re: Restoring Benbox firmware
« on: April 17, 2022, 04:09:49 PM »
I have no idea how to restore the benbox firmware. Overwrote my 6 years ago and have no regrets. You could try one of the host applications that interface to standard GRBL. T2 and Lightburn are available with demo options. LaserGRBL is free.

LightBurn is a commercial product with a 30 day evaluation free use period. LaserGRBL is opensource which I think is Windows only. Try both.

Good to hear. Makes me wonder how bad mine is. My 3d printer has a similar non-square problem due to the placement of the belt pulleys in relation to the drive gears. It has a firmware compensation option. BTW - don't see any attached picture.

Nice to hear that you are not "dead"!! I have 3 .of their modules and was hoping they would get into the sharper focused game.

You examined the gcode from BCL to verify that there are no G02 or G03 commands? Just G01. I have a faint recollection of someone optimizing curves from small straight lines to arcs. Ralph is talented enough to do that.

There is a fairly good laser control application called LaserGRBL that runs on Windows and it is free.

I haven't used BCL for at least 5 years. Forgot that it used dfx. I will attempt to convert. Do you use Windows or is there a MAC version?

How do you control the laser? What do you use to generate a CAD file?

Be very careful. I wrote both the svg export code for the png2svg utility and the svg import for my host application. Could have two self canceling faults. Your host may reject the file. This should help remove the source file as the problem. The largest paper I have is 8.5x11. Perhaps taping 4 pieces together will let get it big enough to burn.

Attached is an svg file generated by a home-brew png to svg utility. Not much optimization. Total burn length, outer and inner cuts, is about 3.9 meters. I have a small bug which does not to the last line segment correctly. Manually edited to fix (hopefully).

There are two small lines on either side. About 4 pixels high. Are they needed?

That's too bad. GRBL is not so good on G02. I have 8.5 inch paper and will generate a test via GIMP and a home-brew png to svg vector utility. Can you post a copy of your source file in png or jpg format?

Does the gcode contain a small set of arc commands (G02 I think) or a large number of linear motion (G01) commands?

Nice demo technique.

I built 3 laser etchers, 2 core-xy and 1 rotary. Experimented with with wood, slate, mirrors, anodized aluminum. Built my own host cut & etch host application. All with help and inspiration from this group. When I started I couldn't spell Dyode Lazar.

Seems to have fallen off a cliff. Used to be the most accurate internet discussion group on diode lasers.
